Mazda MX-5 Miata Won’t Start – What Could Be Wrong?

The Mazda MX-5 Miata is a small but efficient car that gets great gas mileage. However, fuel mileage is meaningless if your car won’t start. If your car won’t start, you may be late for work or unable to complete your errands on your day off.

So, what could be the problem? Several things could go wrong. But first, let’s take a look at the most common causes of this problem, as well as the warning signs of each.

Battery Failure

This is most likely one of the most common reasons why people believe their Mazda MX-5 Miata will not start. This can happen for a variety of reasons, but it is most commonly caused by the age of your vehicle.

Batteries typically last three to five years, depending on how well they are maintained. Though this lifespan varies, it provides an indication of how long your battery should last.

If you notice that your car is taking longer to start or is completely dead, it may be time to replace the battery. The first thing you should try is jumpstarting the battery.

If that doesn’t work, you can take the battery to an automotive store to have it checked. They will be able to tell you whether or not the battery needs to be replaced. That implies that there is something else wrong with the vehicle.

Battery Terminal Corrosion

If your Mazda MX-5 Miata’s terminals are corroded, it could have electrical problems or fail to start. The battery wires must be unplugged, and the terminals must be scrubbed with a wire brush and baking soda. When you’re finished, tighten them to make sure they’re reattached properly.

Faulty Alternator

The alternator is in charge of powering the battery and other electrical components in the vehicle. If your alternator fails, it may be unable to meet the demands of starting your car.

Dimmed headlights while driving or the battery light coming on are two signs that your alternator is failing. Furthermore, components such as your radio and air conditioning will be turned off.

If you notice any of these symptoms, take your car to a mechanic to have it checked.

Starter Motor Failure

The starter motor is in charge of starting the engine. If it’s bad, your car won’t start. There are a few indications that your starter motor is failing. When you turn the key in the ignition, you may hear a clicking noise. Another sign is if your vehicle starts slowly or not at all.

A Defective Starter Solenoid

If your starter starts slowly or the engine continues to turn over, you have a bad starter solenoid. The solenoid may become rusty or jammed, which makes it less effective.

Negative Starter Relay

A faulty starter relay is another cause of your Mazda MX-5 Miata not starting. The relay is in charge of supplying power to the starter from the battery. If the relay fails, your Mazda MX-5 Miata may not start, or if it does, it may take some time to catch up.

Worn Spark Plugs

Your car will not start if your spark plugs are worn. Spark plugs should be replaced every 30,000 miles. This may vary depending on the make and model of your car, as well as how you drive.

If you’re not sure if it’s time to replace your spark plugs, you can take them to a mechanic, who will be able to tell you whether or not they need to be replaced. When changing spark plugs, it is recommended that you also change the spark plug wires.

Fuel Pump Problems

If you’ve tried all of the simple fixes and nothing works, it’s likely that your Mazda MX-5 Miata won’t start due to a faulty fuel pump. When you try to start it, a bad fuel pump may make a whining noise.

Fuel Filter Clog

If your Mazda MX-5 Miata runs out of gas, it will not start. So, before you do anything else, fill up the gas tank. If you’ve already filled the tank and it still won’t start, you should check the fuel filter. Over time, the filter can become clogged with dirt, preventing the car from running properly.

Loose Battery Connection

If your battery is loose, it will not connect properly to the starter. This could be caused by the car’s vibration or movement. As a result, it’s critical to check the battery connections on a regular basis and tighten them if they’re loose.

Clogged Air Filter

A clean air filter is required for your car’s engine to produce as much power as possible from the fuel it receives from the gas tank. If you’ve never changed your air filter or haven’t done so in a while, this could be why your Mazda MX-5 Miata won’t start.

Check to see if your air filter is clean. If not, remove all of the debris and vacuum it. Then, put it back in the car and try starting it to see if that resolves your issue.

Blown Engine

If you blew a fuse, it means that an electrical component in your car is not receiving power.

A blown fuse usually has visible signs. One sign is when one or more of your vehicle’s electrical components fail. Another indication is if the fuse box is warm to the touch.

Final Thoughts

You will have problems, just like any other car, at some point. The Mazda MX-5 Miata is no exception in this regard, and it is possible that it will not start. If this occurs, begin with the basics by checking the battery first.

Proceed down the list to troubleshoot the problem. If you are feeling overwhelmed, seek assistance from a reputable certified mechanic.
